Preparing the Machine

Preparing the Machine

  1. Park the machine on a level surface.

  2. Shift to the NEUTRAL position.

  3. Lower all attachments (if equipped).

  4. Engage the parking brake.

  5. Shut off the engine and remove the key.

  6. Disconnect the battery; refer to your machine Operator’s Manual.

Installing the Manifold

Parts needed for this procedure:

Manifold1
Switch2
Carriage bolt (5/16 x 1 inch)2
Locknut (5/16 inch)2
Male coupler1
Female coupler1
Bolt (5/16 x 3/4 inch)3
12V port1
Hydraulic tube1

  1. Install the male and female hydraulic connectors to the manifold (Figure 1).

  2. Remove the plastic nut and use it to connect the 12V port to the bracket (Figure 1).

  3. Install the bracket to the manifold with 3 bolts (5/16 x 3/4 inch); refer to Figure 1.
